[BUG] Korean IME composition fails in Quick Launcher (Option+Space) on macOS

[sangmandu]

Description

When typing Korean (Hangul) in the Quick Launcher (triggered by Option+Space), characters are lost during the IME composition process.

Korean input requires a composition buffer where consonants (초성), vowels (중성), and final consonants (종성) are combined before being committed. However, in the Quick Launcher, intermediate characters disappear during this composition process.

Steps to Reproduce

1. Open Claude Desktop on macOS
2. Press Option+Space to open the Quick Launcher
3. Switch to Korean input method
4. Try typing "오늘 무엇을 도와드릴까요?" (a common Korean phrase)

Expected Behavior

The text should appear as typed: 오늘 무엇을 도와드릴까요?

Actual Behavior

The text appears broken: 오ㄹ 무ㅅㅡ 도ㅏㅡㅣ까?

What's happening:

• When typing "오늘":
  1. Type "오" → "오" appears ✓
  2. Type "ㄴ" → "온" appears in composition buffer
  3. Type "ㅡ" → At this moment, "오" gets committed but "ㄴ" disappears, only "ㄹ" from the next syllable remains
• Result: "오늘" becomes "오ㄹ"

This pattern repeats for each syllable, causing every other character to be lost.

Environment

• OS: macOS (Darwin)
• Claude Desktop: Latest version
• Input Method: macOS default Korean input (2-Set Korean)
• Trigger: Quick Launcher via Option+Space

Additional Context

• This issue does NOT occur in the main Claude Desktop window (opened from Dock)
• This issue ONLY occurs in the Quick Launcher overlay
• This appears to be related to known Electron IME issues when windows are focused programmatically:
  • [Bug]: Tray click event cause CJK input issue on Mac OS electron/electron#32307 (Tray click causes CJK input issue)
  • IME got wrong position when focus window with BrowserWindow's api on macOS mojave. electron/electron#14834 (IME position bug on focus)

The Quick Launcher likely uses a similar mechanism (overlay/tray-like window focus) that triggers the Electron CJK IME bug.

Workaround

Currently, the only workaround is to use the main Claude Desktop app instead of the Quick Launcher for Korean input.

I am a Korean user. The Quick Launcher is convenient, but I rarely use the desktop app because it is not very convenient for Korean. Please fix this issue as soon as possible.
